The popularity of f3 has completely opened up the sales of Nanshan 1.0t engine.

As the general manager of Nanshan Engine, Cheng Tao is naturally in a very good mood.

"Mr. Cao, our 3.0t twin-turbocharged engine production line has been built. After debugging for a period of time, formal mass production can begin."

"In addition, the prototype test of the W12 engine has also been completed. After re-modifying the drawings of some parts, we can enter the mass production preparation stage."

"As for the 1.5t and 1.0t engines that have been mass-produced, their current production capacity and load are relatively high."

"There is only a 2.0t engine production line, and the capacity utilization rate is less than 50%."

"According to the current situation, basically the main research and development work of the engine has been completed."

"We will soon be able to form a series of engine products of 1.0t, 1.5t, 2.0t, 3.0t and 6.0t."

"But I feel that there is a lack of a V8 engine with a displacement of about 4.0t."

"Our Xingchen 2 currently plans to use a 6.0t engine, but if there is a 4.0t low-end version, it may be able to take sales to a higher level."

"Similarly, Xingchen 1 uses a 3.0t engine, although there are plans to install a 6.0t high-performance version in the next step."

"But a 4.0t V8 engine may actually be more suitable for it."

Nanshan Engine must continue to develop new engines in order to have the possibility of progress and expansion.

Publicly and privately, Cheng Tao hopes to develop more engines.

Not only can Xingchen cars be used, but they can also be sold to others to make money.

"Mr. Cao, I also think there is a certain need for research and development of the 4.0t V8 engine."

"With it, our 3.0t engine can be considered for small-scale external sales in the future."

"Once Xingchen 2 is successful and everyone sees the charm of large SUVs, domestic independent brand car companies may immediately follow up and launch large SUVs."

"Although the 2.0t engine can also be used to match it, the 3.0t is obviously more suitable."

"At the same time, with the emergence of V8 engines, it has become possible to directly develop a high-horsepower W16 engine by using the same camshaft method as the two V8s, similar to the W12."

"It will make sense for us to launch more high-end models in the future."

Even though Zeng Tingting is only 155cm tall, she likes big cars very much.

The future Xingchen No. 2 is the model she particularly wants to buy.

"What Minister Zeng said makes sense. After we have V8 and W16, the displacement of the engine is basically enough."

"We only need to make some more modifications on this basis in the future to meet the needs of the next ten years or so."

Cheng Tao glanced at Zeng Tingting gratefully.

Compared with popular engines like the 1.5t, the input-output ratio of the V8 engine is definitely worse.

And there are no plans to sell it externally in the future.

Under such circumstances, it is not easy for Zeng Tingting to stand up and support his views.

"Our engine R&D team has accumulated some experience."

"In addition to developing products with larger displacements, the next step is to carefully study the engines suitable for hybrid models."

"Whether it is the FHEV route that Toyota and Honda are taking, or the PHEV route, the future is quite promising."

"Besides that, have you ever considered looking into diesel engines?"

Cao Yang's question was a bit beyond Cheng Tao's expectation.

When it comes to hybrid engines, he can understand it.

After all, strictly speaking, the engine used on Xingchen 3 can be considered a hybrid engine.

But as for the diesel engine...

As we all know, China's diesel engines can be said to be "unpopular" or even "disliked"!

First of all, in most people’s minds, diesel engines are basically tractors that emit black smoke, or rumbling heavy trucks. Moreover, the impression of diesel engines in the minds of Chinese people is that they emit black smoke.

,noise,vibration,cumbersome!

But in fact, diesel engines are more suitable for our domestic road environment.

Although the speed is not fast and the driving is stop-and-go, the diesel engine's low speed and high torque can just be used, and it is more energy-saving.

In some European and American countries, diesel engines are even more popular than gasoline engines.

Some organizations have made statistics and found that in Europe, which has stricter vehicle exhaust emission requirements, the penetration rate of diesel vehicles can reach more than 60% in a few years, but in China it is less than 1%.

"Mr. Cao, there is no future application of diesel engines in passenger cars, right?"

“Are we going to produce heavy trucks in the future?”

Seeing that Cheng Tao was a little confused, Zeng Tingting couldn't help but ask this question for him.

"In the future, both our own models and those of other independent brands will definitely go overseas."

"Due to poor oil quality in China, diesel-engine cars really have no future."

"But it's different abroad. The advantages of diesel engines are still very obvious."

"The first thing is to save fuel."

"The energy conversion rate of a compression-ignition diesel engine is higher than that of a ignition-type gasoline engine. Therefore, for diesel engines and gasoline engines of the same model or the same displacement, diesel engines are more fuel-efficient."

"The second thing is that the torque is large and the strength is sufficient."

"The diesel engine is very powerful even at low speeds. This is worse than the gasoline engine when carrying heavy loads, climbing hills and off-road. Of course, the performance on high speeds is not as good as that of gasoline vehicles."

"The third is to save money, which is something independent brands care about. After all, diesel engines have simple structures and low maintenance and maintenance costs."

Cao Yang's explanation naturally makes sense.

However, Cheng Tao couldn't help but retort: ​​"Mr. Cao, as you said, the diesel engine does have these advantages, but its shortcomings are also very obvious."

"First, diesel vehicle engines have high technical content and require high machining accuracy for many parts. However, many mechanical manufacturing processes of domestic auto parts companies are still not up to standard."

"For example, the fuel supply pump and fuel injector on a diesel engine are processed with extremely high precision, but on a gasoline engine, there is no high matching accuracy requirement between these two parts."

"Second, diesel vehicles have high torque and low speed, so they need a gearbox with multiple speeds and a speed ratio that cannot jump too much between each step. There are no very good products in China for this."

"Our Nanshan Transmission is considered the most powerful transmission company in China, but we have not researched products in this area."

"Another very critical and most important point is policy-related things."

"This is something neither businesses nor consumers can change."

"That is diesel, which is a strategic material. Freight vehicles on the street use diesel, and some large equipment used in industrial production also use diesel."

"In addition, things like airplanes, ships, and tanks also use diesel."

"China is not rich in oil resources, so we still have to rely on imports."

"After the imported crude oil is refined, part of it will be diesel and part of it will be gasoline. Diesel itself is a very important industrial material and strategic material. If all private cars are filled with diesel, then there will definitely not be enough diesel, and

The extra gasoline will be wasted.”

"So I think it's not a good direction to spend a lot of R&D resources on diesel engines."

Cheng Tao has worked in Nanshan Group for several years and has a certain understanding of Cao Yang's character.

If you know this situation, you can just say what you have to say without having to think too much.

"Mr. Cheng, what you said makes sense, but our diesel engines are mainly aimed at the future export market."

"I believe that when the time comes, independent brand car companies such as Great Wall Motors and Chery Automobile will be interested."

"As for technology and processing issues, they are a problem for other companies."

"But for our Nanshan Group, this is not a problem at all."

"Nanshan equipment is now able to produce some five-axis CNC machine tools. Are you still worried that the accuracy of the parts will not meet the requirements?"

"As for technology, when we first developed the 1.5t engine, our technology accumulation was much weaker than it is now, so we haven't developed it yet."

"Now you are worried that you won't be able to do it?"

Cao Yang is obviously optimistic about the development of diesel engines.

The main thing is that this thing can be used not only on passenger cars.

Even twenty years later, many heavy trucks and special vehicles will still need to use diesel engines.

After Nanshan Group further develops, it is inevitable to expand related businesses.

How can we expand our business in the future without accumulating some related technologies?

"If we want to study diesel engines, I think we should consider studying those used in trucks first?"

"That way we can sell it to some domestic companies relatively quickly."

"If it is used in passenger cars, I think there won't be any demand in the short term."

Zeng Tingting gave her own suggestions from a sales perspective.

After all, if the diesel engine is developed by then, she will be needed to be responsible for sales.
